在pH3.8的醋酸盐缓冲溶液中可得到铀—茜素氨羧络合剂的络合吸附波,铀(Ⅵ)最低检出量达3.0×10~(-7)mol/l。测定了络合物组成为铀(Ⅵ):ALC=1:2。研究证实电极过程为ECE过程。
The complexation adsorption wave of uranium - alizarin amino - carboxyl complexing agent can be obtained in pH3.8 acetate buffer solution. The minimum detectable amount of uranium (Ⅵ) is 3.0 × 10 -7 mol / l. The complex was determined to be uranium (Ⅵ): ALC = 1: 2. The study confirmed that the electrode process is ECE process.
